Although part of security Operating Systems Windows for years, most users do not know what is Firewall nor how it works. In brief Firewall acts as a scut between a computer (Or local network) and Internet, Controlling both the traffic from your computer to the internet (outgoing traffic) And traffic from the Internet to your computer (incoming traffic). For example, the computers connected to the Internet directly through cable (Without the interference of a router) To Public IP addressesIe they can be accessed by anyone on the Internet, which makes any service used on these computers (like the native sharing) Can be accessed from other computers on the Internet. Firewall prevents any type of internet connection, except Accepted user.
Over time, users Windows I get to allow access through Firewall to a large number of applications (Most of which were already removed from the system), which decreases Computer safety. Fortunately for users interested, there is a fairly simple method by which they can reset Windows firewall to the settings default.
